Description
Claims (7)
- 光ファイバーによる非ソリトン光RZパルス列を伝送するように構成された変調器を備えた装置であって、1個のパルスの末尾と、次のパルスの冒頭との位相差が、2π/3〜4π/3であり、各パルスが一定の位相を有することを特徴とし、前記変調器はさらに、パルスの送信と、1個のパルスから新しい各パルスへの位相の逆転をするように構成された、装置。
- 光ファイバーによる非ソリトン光RZパルス列を伝送するように構成された変調器を備えた装置であって、1個のパルスの末尾と、次のパルスの冒頭との位相差が、2π/3〜4π/3であり、位相が、1個のパルスの冒頭と、このパルスの末尾との間で変わることを特徴とし、前記変調器はさらに、パルスの送信と、各パルスへの位相変調の適用をするように構成された、装置。
- パルスにおける位相変化は、位相がπ異なる値の間で連続変化する正弦曲線であることを特徴とする請求項2に記載の装置。
- パルスにおける位相変化は、位相が突然変化する矩形であることを特徴とする請求項2に記載の装置。
- 光ファイバーによる非ソリトン光RZパルス列を伝送するように構成された変調器を備えた装置であって、1個のパルスの末尾と、その直後のパルスの冒頭との位相差が、2π/3〜4π/3であることを特徴とし、前記変調器はさらに、第一の位相を持つパルス周波数2分の1のパルス列の送信と、第二の位相を持つパルス周波数2分の1のパルス列の送信と、パルス周波数2分の1の2個のパルス列のインターリーブとをするように構成された、装置。
- 各パルスが一定の位相を有することを特徴とする請求項5に記載の装置。
- 偶数次のパルスの位相と奇数次のパルスの位相との差が、2π/3〜4π/3であることを特徴とする請求項6に記載の装置。
